“I’m disappointed that things didn’t work out because this is a special organization and a great place to be,” McCoy said in a statement released by the team. “I want to thank Vance for the opportunity he gave me and the entire organization from Mr. B all the way on down.

“I appreciate the hard work of our players and was proud to work with them along with the rest of our coaching staff. My family and I loved it here, and I’m very thankful for my time with the Denver Broncos.”

McCoy, 45, coached Denver’s offense from 2010-2012 and returned as offensive coordinator after the team hired Vance Joseph in January. The Broncos averaged just 18.3 points per game through the first ten games of the season, the ninth-worst total in the NFL.

The Oakland Raiders averaged 26 points per game with Musgrave serving as their offensive coordinator last season, the seventh-best average in the league. The team filled Musgrave’s former position by promoting offensive assistant Klint Kubiak to quarterbacks coach.
